“It's great Americana is what it really, really is,” he says of his brother's iconic songs. His favorite Frankie Valli songs to perform include “Can't Take My Eyes Off of You,” “Swearin' to God,” “My Eyes Adored You” and “I've Got You Under My Skin.” You should judge a singer by his tonality, by his phrasing, by the love that he puts into the song and by his emotions.” You shouldn't ever judge a singer by how high he sings. It puts a lot of stress on the vocal chords. That's a gimmick style,” he says by phone from his home in Bloomfield, N.J. “My favorite Frankie Valli songs are not the falsetto songs. While their sounds are genetically wired to be similar, Bobby describes himself as “more of a singer,' using a fuller head voice for the high notes, instead of switching into falsetto. He typically opens with a medley of Frankie's songs and tells stories about his big brother, who churned out hits from “Sherry” and “Big Girls Don't Cry” in 1962 to “December, 1962 (Oh, What a Night)” in 1975 with The Four Seasons, as well as a slew of solo efforts. Frankie Valli's biggest fan is taking the Jersey boy's music on the road, mixing in his own tunes, too.īobby Valli, 15 years younger than his oldest brother, is bringing “Valli to Valli: A Tribute to the Jersey Boys” to the Riverside Casino Event Center at 4 p.m.
